More Information

Jimmy Green 10mm MF Grade 40 Hot Dip Galvanised Calibrated Anchor Chain is sourced exclusively from MF Catenificio Frigerio.

MF Catenificio chain is manufactured, hot dip galvanised,and proof tested in their modern research, test and production facility located near Lecco, Lake Como, Italy.

The proof load testing process ensures that each individual weld has been completed successfully.

MF Calibrated Anchor Chain features enhanced Solid Zinc Galvanising treatment with greater micron depth and prolonged protection against corrosion.

MF Solid Zinc Galvanising

MF have developed an enhanced Solid Zinc Galvanising treatment in conjunction with the standard hot dip galvanising process.
Solid Zinc Galvanising is an MF duplex treatment where both aspects of the process are complementary hot dip molten zinc galvanisation.
The improved coverage, micron depth and adhesion properties extended the effective working life of the galvanising by up to 25%.
Solid Zinc galvanising has a relatively bright appearance before being exposed to the elements.

Check your calibration:

10mm Calibrated Anchor Chain is available in two different calibrations - ISO4565 (10 X 30) AND DIN766 (10 X 28)

It is very important to check the size and calibration of your gypsy/chain before you order

If you are unsure we can help you to decide - we will take all reasonable steps to ensure you get the correct chain.

The simplest way to check that you are buying the correct calibration is to take a measurement from your existing chain, providing of course that it fits correctly.

We measure 10 links because, in practice, it is difficult to measure one link accurately enough.
The links should be laid out flat and pulled tight.
Measure from the outside edge to outside edge.


N.B. The measurement for an old chain may be a little longer than new due to a degree of wear and elongation in use.

10mm MF Grade 40 Anchor Chain is generally suitable for yachts up to approximately 16 metres, length overall
Factor in:
Displacement : Length ratio
Your cruising intentions
The anticipated anchorage conditions e.g. depth, seabed holding characteristics, the length of fetch and degree of exposure to prevailing winds
The length of chain that will be deployed and any extra scope provided by an anchor warp
The weight and design of anchor.

Your anchor rode is only as strong as the weakest link so ensure that all your connectors and shackles are rated to the requisite break load.

Maximum Pin Diameter refers to the largest pin which will just fit into the end link of 10mm DIN766/ISO chain

Select the largest possible galvanised shackle or anchor connector by pin diameter to fit the chain.

Quality Control and Accountability
Every length of chain is checked and labelled with the manufacturer, the date received and a corresponding batch number when it arrives.
The batch number is then recorded at the point of sale.
Every chain order is therefore traceable and accountable to the Manufacturer Test Certificate.
A copy of the corresponding MF Catenificio Test Certificate is available with your order on request.

MF chain manufacturing has Lloyds Register approval to the ultimate ISO 9001 quality standard:
